Help understanding reduce-reduce conflict

The language I'm building a grammar for is generating a reduce-reduce conflict and I'm not sure how to read the conflict. I'm assuming in this case I should insert a ReduceHere() call somewhere in my grammar to clear up the conflict but I lack the understanding
currently to know where this goes and exactly why (I assume it to be a conflict between potential expressions using ++, +, -- and -). The conflict message is as follows:

My grammar includes operators common to C# such as ++, --, ==, !=, etc. as you can see. I used the example C# grammar in irony as a starting point. I actually ran into a number of conflicts initially, so I stripped the grammar down to a simplified version with
the intention of slowly adding grammar parts back until I hit a conflict and then solving the conflict. I'm hoping by better understanding this conflict and the proper solution I can apply that knowledge to future conflicts and not nag folks with questions
;). In the current stripped down state the entire grammar is as follows:

Reduce-reduce means there's more than one way some sentence (code) can be parsed (this is called ambiguity). In this case there a sentence where the parser can't decide if the preceding part should be a
Expression or a Unary Expression.

I don't immediately see the problem, but the problematic state is hit with
+1++;. However this shouldn't be a problem because ++ has a higher precedence than
+.

Thank you, that makes sense. I thought it had something to do with that, but every sample I tried parsing came out as I would expect (I'm guessing because of operator precedence as you mention). Am I right to assume that a call to ReduceHere() in the right
spot would solve the conflict?

So this may not be the best approach, but I just tried inserting a ReduceHere() call throughout the expression and unary expression rules and found the following change made the grammar conflict go away:

expression.Rule = primaryExpression + ReduceHere() | binOpExpression;

Also I noticed that the expression +1++ was being parsed as (+1)++ and now it is being parsed as +(1++). I'm not going to pretend to fully understand why the ReduceHere() call fixes it when placed in that particular spot, but that should still help me debug
further reduce-reduce conflicts. Thanks again for the help.
